These aluminum trailers have everything you need to get you, your family, and your ATVs to the trails safely. Rear ramp door with spring assist for easy loading and two front access doors to easily tie down your ATVs. A full stone-guard front, screwless aluminum sides, and a seamless aluminum roof help keep this trailer looking sharp. Full length tie-downs rails welded to the frame with quick-adjust (QA) eyebolts mean you're not going to be pulling up plywood when you're strapping down your ATVs. Our LED trailer lights are incredibly bright to make sure that you and your trailer are seen at night. And don't forget, this is a fully enclosed ATV trailer built on a rugged 2" x 5" tubular main frame with 2" x 3" tube floor cross members 24" on center. Wall uprights and roof cross-members on 16" center to ensure they'll handle the New England snow load. This is an extremely rugged enclosed ATV trailer that will last you for years to come.
